drm/xe/configfs: Add disable_vram_page_offline attribute

Browse source

Add a new configfs attribute 'disable_vram_page_offline' to control
how bad VRAM pages are handled:
  0, n, N, false - Do not disable (Offlining is active - default)
  1, y, Y, true  - Disable vram page offline (Logging only)

The attribute can only be set before binding to the device and defaults
to false (offlining enabled). This gives administrators control over
whether corrupted VRAM pages detected by hardware (e.g., ECC errors)
are actively offlined or only logged.

v3(Sashiko):
- fix doc
v2(Sashiko):
- keep default value in case configfs not present
